why sometimes new file is not added to vault automaticly
You will likely get a faster/better answer by providing more details - are you using WPDM, PDM std, PDM Pro or something else? I suspect that whichever you are using, there may likely be a setting to enable the file to be added automatically.
Please check your connectivity to the PDM servers. Sometimes if your connection is interrupting the PDM cannot send a first copy of the file to the archive server and then your files stay as a local files. The very simple check is running cmd and then put: ping <archive-server-name> -t.
If PDM Standard - if you are Offline, and create a new file and save it to the local vault location. When you go back online, it won't be added. You have to take the proactive step of "adding to Vault" and this can only be done in the Windows Explorer window (outside of SW.)
